Why the Highest Piano Notes Have Short Strings
The steel used for piano wire has a breaking (tensile) strength of about and a density of .

Part A
What is the speed of a wave traveling down such a wire if the wire is stretched to its breaking point?
Express the speed of the wave numerically, in meters per second, to the nearest integer.
=______________ m/s

Part B
Imagine that the wire described in the problem introduction is used for the highest C on a piano ( ). If the wire is in tune when stretched to its breaking point, what must the vibrating length of the wire be?
Express the length numerically, in centimeters, using three significant figures.
= ____________ cm
